Modern smartphones with bright displays and colorful interfaces deliberately stimulate the production of dopamine, forcing us to spend extra hours on gadgets. Setting your device to black and white mode (Grayscale) is a proven way to reduce the visual appeal of your content and reduce your reliance on endless feed scrolling. This approach helps to return the focus to real tasks and reduce the time of “sticking.”
In the operating system Android this function is implemented at the system level, so turning it on does not require root access or complex manipulations with the firmware. Depending on the OS version and the installed manufacturer's shell, the activation method may differ. We will look at all the current methods, from standard settings to hidden developer menus.
Why monochrome? The fact is that our brain instantly reacts to red notifications and bright icons, perceiving them as a signal to action. Turning off the color turns a smartphone into a utilitarian tool, depriving it of its entertainment component. This is the first step to a digital detox, which can be implemented in a couple of clicks.
Using special features (Digital Wellbeing)
Starting with version Android 9 Pie, the “Digital Wellbeing” function was built into the system, which includes a sleep mode and an option to change color palette. This is the simplest and safest method available to owners of most modern devices. You don't need to look for hidden menus - everything is publicly available.
To activate, go to Settings → Digital Wellbeing and Parental Controls. Here, find the “Sleep Mode” or “Night Mode” section. In some shells, for example, on smartphones Samsung or Xiaomi, the option to switch to grayscale can be a separate item in the “Special Features” menu. Tapping the toggle instantly discolors the interface.
It's important to note that in Google's standard implementation, this mode is often tied to a schedule. You can set it so that the screen turns black and white automatically at certain times of the day, such as after 10 pm. This helps prepare the brain for sleep, eliminating exposure to the blue spectrum and bright colors before rest.
⚠️ Attention: On some models in the budget segment, the “Digital Well-Being” function may be absent or reduced by the manufacturer. If you do not find this item in the settings, proceed to the next method through the developer menu.
If you want to use the black and white mode only at night, set up a schedule in the "Sleep Mode" menu so as not to change the settings manually every evening.
Activation through the developer menu
If the standard menu does not have the required option, a universal solution would be to use a hidden section for developers. This method works on almost all devices running Android, regardless of the brand. However, increased care is required here, since changing other parameters in this menu may affect the stability of the system.
First you need to activate the developer mode itself. Go to Settings → About phone and find the item “Build number”. Quickly click on it 7 times in a row until a notification appears indicating that you have become a developer. After this, a new section will appear in the main settings menu System → For developers.
Inside this section, scroll down the list to the “Hardware rendering acceleration” or “Monitoring” block. Find the item Simulation of anomalies (Simulate color space). By default it is set to “Disabled”. Click on it and select option Monochrome. The screen will instantly lose all colors.
☑️ Activating developer mode
The main advantage of this method is its globality. Colors are disabled in absolutely all applications, including those that ignore system themes. However, remember that this mode is designed for testing interfaces and not for everyday use, so it may consume a little more processor resources when converting colors in real time.

Settings on Samsung and Xiaomi smartphones
Large manufacturers often add their own add-ons over the standard Android, offering more flexible display management tools. Device owners Samsung with a shell One UI have access to extended screen profiles. Here you can not only make the picture black and white, but also set up filters for colorblind people.
On smartphones Samsung the path looks like this: Settings → Accessibility → Improved visibility → Color filter. Activate the switch and select the Grayscale filter type. A unique feature is the ability to create a shortcut to quickly enable this function through the notification panel, which is very convenient.
Users Xiaomi (MIUI and HyperOS) can also use a similar algorithm. In the section Settings → Advanced settings → Accessibility → Vision there is the “Color correction” option. By turning it on and selecting the “Grayscale” mode, you will achieve a similar effect. The MIUI interface also allows you to configure color inversion, which can be useful in specific reading scenarios.
| Brand / Skin | Path to settings | Function name | Quick access |
|---|---|---|---|
| Google Pixel (Stock) | Settings → Digital well-being | Sleep mode / Grayscale | Through schedule |
| Samsung (One UI) | Special features → Improving visibility | Color filter | Shortcut in the curtain |
| Xiaomi (MIUI/HyperOS) | Advanced settings → Accessibility | Color correction | Through the vision menu |
| Any Android | For developers | Simulation of anomalies | No (menu only) |
Impact on autonomy and eye health
There is a widespread belief that a black and white screen significantly saves battery power. This is only partly true and depends on the type of matrix of your display. If you have a smartphone with a screen AMOLED or Super AMOLED, then turning off bright color pixels really reduces power consumption, since the black pixels on such matrices are physically turned off and do not consume energy.
In the case of IPS screens that use constant backlighting, the savings will be minimal or non-existent. The backlight continues to operate at the same brightness, regardless of what color is displayed on the matrix. Therefore, you shouldn’t count on a significant increase in operating time just by turning on the monochrome mode on IPS.
As for eye health, reducing color reduces the overall load on the optic nerve. The brain does not need to process unnecessary visual information, which reduces fatigue when reading text for a long time. This is especially true in low-light conditions, where the contrast between a bright screen and a dark room is most harmful.
⚠️ Attention: Grayscale mode is not a replacement for a full-fledged Night Light filter. For maximum vision protection at night, it is recommended to use both functions simultaneously: a warm screen tint plus the absence of saturated colors.
Use of third-party applications
If system methods for some reason do not suit you or require too many steps to enable, you can use specialized software from the store Google Play. Applications like Grayscale Mode or DayNight allow you to create complex mode switching scenarios.
Such utilities often use an accessibility service to impose a color filter on top of the entire interface. This gives you flexibility: you can set the screen to turn black and white only when you launch specific applications, such as Instagram or TikTok, leaving other apps in color.
However, installing third-party software has its own risks. Applications require broad permissions to access the system, which could theoretically reduce data security. In addition, constantly running the filtering service can increase RAM consumption and drain the battery faster compared to a built-in system solution.
How do filter applications work?
They create a translucent layer with a specific color on top of all windows or use the system API to change the rendering color scheme. This may cause slight delays (input lag) when touching the screen.
Returning to color mode and possible problems
Returning everything to its original state is as easy as turning off the colors. You just need to follow the same path in the settings and turn the switch to the “Off” position or select the “Disabled” mode in the anomaly simulation menu. If you were using a third-party application, just uninstall it or revoke access rights in the Accessibility settings.
Sometimes users encounter a situation where colors do not return even after disabling the feature. This may be due to the interface rendering process freezing. In this case, the usual rebooting the devicewill help. It will reset all temporary graphics settings and return the display drivers to normal operation.
In rare cases, certain applications may display content incorrectly in monochrome mode. Pictures may appear grainy and videos may appear unnaturally dark. This is a feature of color space conversion, and this can only be corrected by temporarily disabling the filter while viewing multimedia.
⚠️ Attention: Smartphone manufacturers' interfaces are regularly updated. The names of menu items may change in new versions of Android or shells. If you do not find an exact match, look for sections with similar meaning related to “Display”, “Vision” or “Accessibility”.
The system method through “Digital Wellbeing” or “Accessibility” is the most stable and energy efficient solution compared to third-party applications.
Frequently asked questions (FAQ)
Does black and white mode affect the quality of photos in the camera?
No, this setting only affects the display of the interface and content on the screen of your smartphone. The camera will continue to shoot in full color and the photos in the gallery will be in color. However, when viewing captured photos in the gallery, they will also be displayed in grayscale while the mode is active.
Is it possible to make only the icon of a specific application black and white?
This cannot be done using standard Android tools - the mode is applied globally to the entire system. However, some launchers (desktop shells) allow you to change icons individually. There are also third-party applications that can apply the filter selectively to the windows of certain apps.
Will this mode help save Internet traffic?
No, switching to monochrome mode does not affect the amount of data transferred. Pictures and videos are still downloaded in full color from the servers, it's just that your screen displays them without color. Saving traffic is only possible when you enable the “Data Saver” mode in the network settings.
Why did the screen become dim after enabling the mode?
Often, the “Grayscale” mode is automatically activated along with the “Do Not Disturb” or “Energy Saver” mode, which also reduces the brightness of the backlight. Check your brightness settings manually. In addition, to the human eye, a black and white image may appear less contrasty and dull compared to a color one.
Will the fingerprint scanner work in black and white mode?
Yes, the operation of biometric sensors, including fingerprint scanners and face unlock, does not depend on the color rendering of the display. These systems operate at the hardware level and continue to function normally regardless of the interface settings.
